He has always planned to run as an Independent and siphon votes away from the Republican candidate.
Do you actually think Trump (who is top in the polls) would drop out so that worn out old bag-o-bones could win.
Trump plays second fiddle to no one. Just ask him.
However, if he does begin to have trouble and realizes he can't win, he will throw his support behind Cruz.
“Donald Trump is Hillary Clinton’s stalking horse.”
How is that anywhere logical? He is leading in the Republican primaries, loudly proclaiming policies that are anathema to Hillary Clinton. And, Trump, who supposedly has the biggest ego in the world, and is winning, willingly throws it ALL at the feet of Hillary.
If in proclaiming those POLICIES, which you have to agree are correct, he loses the primaries, then the country is lost already. The election of Hillary, or whichever RINO picks up the pieces, will be irrelevant. Immigration is the thing; if it is not stopped, we are finished. Demographics is destiny. The following twenty years will be food fight by foreigners feasting on what Americans have built. Then, it is over. Maybe the remaining Americans can comfort themselves in their destruction by reminding themselves that they were not racist.
If it's Yeb, so be it. No difference between Yeb and Hillary anyway.
