Republicans are not going to get excited about these special elections, especially in dark red districts. The media, including Fox News are trying to sell more Corn Flakes by trying to beat the drum about the narrow margin.
Bottom line is that the Media continue to hate Trump and the professional political operatives are trying to drum up business from both sides. I don’t think that this carries over to the November election.
Trent Franks, the GOP incumbent who resigned this seat, left in disgrace, and scandalized incumbents tend to leave a bad taste in voters’ mouths for electing someone of the same party, which perhaps partially explains the less than enthusiastic margin for Lesko.
