A series of primaries in early May in deep-red territory in Indiana, Kentucky and Louisiana could reveal the waning influence of President Donald Trump's influence over the Republican Party. The results could be seen as a stark indication that the president's sway over the GOP is waning as his popularity increases. While not explicitly opposing Trump, these candidates have downplayed their differences with him, their victories could allow other Republicans to distance themselves from him as they run for reelection in November. One candidate, Ed Gallrein, has benefited from a surge in cash from Trump-directed forces, with groups attacking him and boosting his opponent.
