There's that number again, 47%.
Of Trump's popular vote to date, that's only 3.7 million Trump voters rebelling against the Republicans.
Remember Rush's Limbaugh's "4 million stayed home in 2012"?
Ken Blackwell, quoted here:
“As far as my objective of forcing this into a contested convention, I feel very optimistic about it," said Ken Blackwell, the former Ohio secretary of state who is working with a pair of anti-Trump groups, including Our Principles PAC, which paid for the Wisconsin billboards. ...
Blackwell said he wasn't concerned about a Cruz convention victory splitting the party, as long as the process was “transparent.” He also said the party could afford to alienate new voters Trump is bringing to the party—Blackwell referred to them as “undocumented Republicans”—because the traditional base would be motivated to stop Clinton.
“Folks will get over it,” Blackwell said. “The prospects of Hillary Clinton naming a liberal justice to the Supreme Court, expanding our welfare state and furthering our incompetence in international affairs will drive out the old base that didn't come out for Romney.”
