Republican worries of a midterm flop are growing heading into the critical post-Labor Day campaign season, with analysts who had previously predicted massive GOP gains shifting their forecasts toward Democrats. Rick Tyler, a Republican strategist and analyst, said the environment looks “not even close” to a red wave election year. “The enthusiasm is just not there,” Tyler said. “Last time Republicans had a good year, they were six points ahead in the generic poll. Now we’re barely two points ahead. So it’s definitely not going to happen.”
