Hosts like Ingraham and Rush Limbaugh have great sway over many of the voters who show up to GOP primary elections, even if conservative talk radio itself has taken a ratings plunge in recent years.

“There is no doubt that talk radio will have an influence on primaries as they roll through the calendar,” said GOP strategist Bill Cortese. “Everyone is trying to be a kingmaker.”

And many of them really hate Jeb.

“[W]hen you compare their positions, Hillary Clinton and Jeb Bush, on the key important issues, they are two peas in the same pod,” Rush Limbaugh said on his show shortly after Bush began laying the groundwork for a campaign. “He doesn’t want to have to sell his soul for the tea party vote. What that means is, he doesn’t want to have to pretend to be a conservative at any time during the primary to get the tea party or conservative vote.”
