The reason this perception exists to a such a high degree is that the liberal politicians relentlessly hammer it home with thousands and thousands of commercials during campaign season, and liberal media convey the message both overtly and subtly in dozens of ways.
It infuriates me.
99% of the Republican National Convention was not shown on network TV and certainly not shown on CNN and PMSNBC. And only a portion shown on Fox. The part none saw were all the couples that came on stage to talk about Romney and all that he has done for others. From donating money people he never layed eyes on to giving thousands of dollars to VA hospitals, to paying for operations for terminally ill children. None of this was shown on national TV. If you wanted to see it you had to watch the convention on C-Span. The slobbering love affair the media has with the Kenyan did as much to defeat Romney as rigged voting did.
