Within the evangelical community, Dr. Dobson's voice still carries weight. His endorsement is a blow to Santorum and Huckabee, but they may actually be running for a Cabinet position. Dobson will not help Cruz in the general election, but the Texas senator is running for the Republican nomination. His main opponent is Donald Trump, who is a PINO (Protestant in name only), twice divorced and an advocate, until recently, of abortion on demand. Cruz's evangelical bona fides are strong; he speaks their language fluently. Trump is as clueless as any New Yorker is on the Southern/Lower Midwestern evangelical world, except for the minuscule number of evangelicals locally.
If and when Santorum, Huckabee, and Carson drop out, Cruz will likely inherit most of their votes, important in the case of Carson, less so for the other few. To have a chance to win, Cruz must win in his home state and the rest of the South, plus states like Kansas and Colorado. Being the main choice of evangelicals will be a great help.
The Trump fans don’t like to admit it but Trump is also leaking voters to Cruz. The Luntz focus group after the last debate said that 11 of them would switch their support after seeing the debate. Most said they would switch from Trump to Cruz with one or two Rubio to Cruz, a Paul to Cruz and a couple that made no sense whatsoever like Fiorina to Chrstie.
Most important was the woman who said she switched because seeing Trump and Cruz side by side drew a clear contrast and Ted Cruz was clearly the one who appeared presidential.
The Christian Right has been a catastrophic failure, and is largely responsible for America’s leftward movement since 1988.
Any candidate for national office associating with them has a death wish.
