Bill Clinton knows a lot about the White House. And, without a doubt, if there's one person who knows the Democratic Party's presidential nomination frontrunner more than anyone from her campaign block, he's got to be the man.

This makes him a powerful drumbeater for Hillary Clinton's campaign as people tend to listen to someone who knows exactly what he says. The Hillary team is doing a good job in making sure his voice will be heard.

Bill Clinton Tries to Win Over Illinois Voters

Ahead of the Illinois primaries, the former president delivered a speech to rally support for his wife's cause on Tuesday, March 8, 2016, at Beth Emet Synagogue in the suburban city of Evanston in Cook County.

The gist of Bill's rallying cry for Hillary is that she's the one candidate whose victory means a triumph for all Americans. "She's running for president to put everybody in the picture. She's running for president so we can all rise together," he said. "The most important reason to vote for her is that we cannot wait any longer. Finally, we can rise together."

The Hillary-Clinton-Over-a-Republican-Candidate Argument

The former president also touched on making a case for the Democratic cause. "This country will never have inclusive economic growth...and have inclusive politics if you have a Republican president, a Republican Congress and Republican Supreme Court," he said.

Bill also said that for everything that his wife has accomplished in Washington, there has always been some measure of support from the Republican side. He also went so far as to say that the GOP candidates are fazed by her wife's presidential bid.

"They're scared to have to run against her, because they know if she becomes the president, she'll be the grown-up in every room, and she'll find a way to get them to do something good for America," he said.

On Meeting Hillary for the First Time

More than four decades ago, the couple met each other in March for the first time. "I was just blown away. I had never seen anybody who seemed to have a better sense of where we were at the time. What we were trying to do and how to get stuff done," Bill said.

On the course of his 45-minute monologue, the former White House boss referred to his wife as "the best change maker" he has ever known.

Meanwhile, as previously reported, a Change.org petition was asking for the arrest of Bill for allegedly breaking the Massachusetts election laws on Super Tuesday. The petition has since garnered more than 100,000 supporters.
