President Donald Trump's campaign team has filed several lawsuits against swing states regarding this year's election results.

The cases alleged that ballots had errors as voters were required to use Sharpie pens and observers not having enough access to monitor ballot counting, and late mail-in ballots were improperly mixed with legal votes.

Judges have already dismissed most of the cases quickly, often due to a lack of evidence.

One of its most recent filed federal suits is in Pennsylvania, claiming that voters were treated differently based on whether they vote by mail or in-person. The complaint alleged that this created an unconstitutional "two-tiered" system. 

Pennsylvania

The Trump campaign claimed that mail-in voting did not include the same safeguards as in-person voting. They alleged that the mail-in voting had stringent safeguards that include adequate verification of voters' identities and monitoring by observers. 

The lawsuit seeks a temporary injunction preventing the state of Pennsylvania from certifying its election results, as reported by USA Today.

The lawsuit involves a challenge to a Pennsylvania Supreme Court decision that implemented a three-day extension of the deadline for accepting mail-in and absentee ballots.

The Secretary of State's office said the extension was a reasonable accommodation for voters due to the COVID-19 pandemic and mail delays. The Pennsylvania Supreme Court upheld the extension.

A few other Republican candidates filed complaints, saying that county boards of elections had violated the state's election code by contacting voters who had made mistakes in their ballots.

The Republicans argued that this gave them opportunities to "cure" the ballots by making corrections. These lawsuits have not progressed in disqualifying ballots.

Arizona

The state of Arizona has also received complaints, particularly its Maricopa County, from the Trump campaign.

The lawsuits alleged Arizona voters were given Sharpie markers to make selections, and when vote machines flagged some ballots as defective, poll workers improperly overrode the warnings. The complaints claimed that this resulted in some votes to go uncounted.

As of Tuesday, Democratic presidential nominee Joe Biden led Trump in Arizona by 14,746 votes.

The lawsuit argued that the voters were not informed of the problems of poll workers that processed the ballots anyway.

Arizona's election officials have disputed claims that ballots were tallied improperly. They argued that Sharpie pens work best because they dry instantly and do not smear.

A top state official has called for an independent expert to evaluate the vote count.

Georgia

The state of Georgia also received complaints from the Trump campaign and Georgia Republicans, alleging the Chatham County Board of Elections had improperly mixed ineligible ballots with valid ones. However, the judge quickly dismissed the case the next day for lack of evidence.

Chairman of the Chatham County Board of Registrars, Colin McRae, told the judge that he looked at all 53 ballots in question, and all had been received before the 7 p.m. deadline. 

Michigan

The Trump campaign also filed a lawsuit in Michigan, seeking access for observers to watch ballot counting and allow it to view videotaped surveillance of ballot drop boxes.

A Michigan judge already junked the said lawsuit. The Trump campaign is appealing the case.

Nevada

The Nevada Supreme Court last week declined to stop the counting of ballots in the southern area of Nevada.

The judge said there was little or no evidence to suggest the signature-matching programs were faulty. The judge added that there is perhaps even less evidence to suggest that a human could do the job better.

The federal lawsuit over signature matching also claims that ineligible voters had cast ballots but did not provide any evidence.
