REPUBLICANS CAN DUMP TRUMP..!

Republican-backed efforts to stop Donald Trump from claiming the party's presidential nomination have flopped over the last four months. Mitt Romney's call for GOP voters to rise up against the real-estate mogul didn't work. Trump easily defeated his Republican rivals in the primaries of late April and early May, forcing Ted Cruz and John Kasich out of the race. Super PACs formed to run ads against Trump in the later stages of the primaries lacked cohesion and leadership and failed to attract enough big-money donors. And attempts to attract an independent candidate fizzled.

Unbinding the delegates
Anti-Trump rebels are trying to pass a rule at the Rules Committee meeting Thursday in Cleveland to "codify" the idea that delegates are able to vote their conscious - for whomever they want, even if they are currently bound to Trump on a first ballot.
If that proposal fails, as expected, Trump's opponents are hoping to win over 28 of the 112 Rules Committee members (25 percent) who will be meeting that Thursday to force the full convention to consider whether to unbind the delegates. It's called a "minority report."

Requiring a supermajority to capture the nomination
There's a significant downside to any push to unbind the delegates: It essentially invalidates the five months of Republican primaries and caucuses used to choose the delegates. And many of these GOP leaders could find move unseemly and undemocratic.
So another way to stop Trump at the convention would be for the Rules Committee to vote to require a supermajority - instead of a simple majority - to win the GOP nomination.

Allowing delegates to abstain
A third way how anti-Trump delegates could dump Trump is by abstaining from their vote to keep Trump below the 1,237 number needed for a majority on the roll-call vote.
Ginsberg says that whether a delegate can abstain from his or her vote on a first ballot is likely to come down to a ruling by the chair.
The smart bet is that none of these scenarios is successful. Most Republican delegates, by nature, aren't rebels. They're go-along-get-along party leaders who probably aren't eager to overturn the will of the voters. More importantly, a real presidential alternative to Trump has yet to emerge. After all, it's hard to beat somebody with nobody.
