(AP) — As House Speaker Paul Ryan walks a fine line on Donald Trump — withholding his support, at least for now — some voters back home in his congressional district applaud his effort for the greater good of the GOP. [...] they concede it's unlikely to make a bit of difference in changing the Republican presidential candidate. Dobson, a siding and window contractor, poured two overflowing spoons of sugar into his coffee as he joined his friends at the counter of Citrus Cafe. MSNBC played above the bar, running coverage of Ryan telling a reporter earlier that morning that he would step down as chairman of the Republican National Convention if Trump wants. Miguel Maravillo, a 40-year-old worker at a Mexican grocery store in Janesville who criticized Trump's generalizations about immigrants, said it was brave of Ryan to voice his hesitation. [...] many said they still held out hope that Ryan would change his mind and join the presidential race.
