That is NOT a good sign for front runners ...
Generally, when people remain undecided up to the last minute, they do not vote based on a candidate’s positions on the issues - they chicken out and vote on the “safe” same-old-same old ...
IOW, they will vote for the worst possible establishment hack. This can only be good for Kasich, Bush or Christie. When undecided percentage is this high, then I have doubts as to whether Trump or Cruz will come out on top. Hope I am wrong, but “I got a bad feeling about this.”
Trump is 11 points ahead, Trump voters decided long ago they will not be moved exit polls stated this fact!!! Trump voters are ALSO working!!!
Undecideds according to exit polls breaking heavy for Trump, Kasich.
