Actually, thinking it over, you may be right. Picking Kasich would comfort the GOPe, plus all the RATS who claimed Kasich was the only R they could ever support. Appointing Kasich to a powerless figurehead job like VP would shut him up and appeal to a lot of anti-Trump voters. It might be a smart move.
Right now, the RNC is in a radioactive melt down.
The hate for Trump is in the orgy phase. It will settle down as the new dawn rises. It is apparent the Dems are scared out of their wits when all you hear is Racist, Racist, Racist. They may lose because their candidate is a criminal and they know it. Political correctness will lose, Radical Islam will lose, psycho regulation will lose, the lobbyists will lose, Global Warming will lose, the false charge of Racism will lose, the IRS will lose, false American histories will lose, Black Lives Matter will lose, stupid Baltimore Mayors will lose, illegal aliens will lose, the EPA will lose, the Bureau of Land Management will lose, the politicized Justice Department will lose, the First Amendment will Win, the Second Amendment will Win, the Rule of Law will Win, the right to worship will Win, the people who pay their bills will Win, the law abiding, tax-paying citizen will finally Win!
The entrenched liars, and their minions in the universities and in the dense federal bureaucracies will lose.
