I fully expect Kasich to switch to the Democrat Party in the near future anyway, as it is obvious to me that he is more of a Democrat than he is a Republican. His only real selling point as a Republican was economic based, on social issues he has always been a squishy liberal. Now that he no longer even touts the economic conservative meme, there is no reason for him to remain a Republican.
Took them years, but they finally stopped calling me asking for donations. I can pick my own candidates, thank you very much. They wasted my money, then did what they wanted in DC. Why support them?
