I think Medved is a former Democrat. That would explain his liberal leanings.
Reagan was also a former democrat, einstein.
After Conservatives took over congress for the 1st time in 30+ years with the help of Newt Gingrich and Tom Delay, we saw lots of moderate Democrats switching to the Republican party to enhance their electability.
Now we have lots of liberals in the Republican party, nationwide, that have nothing but contempt for Christian Conservatives and their values.
