He wasn't the one. There is no conservative leader. Trump's demolition of the modern conservative movement is total.
Trump cannot unit conservatives, much less the GOP. He loses 50 states, the Senate, and possibly the House in November.
The GOP is a non-viable party within three years. The GOP-e killed the party, but Trump applied the coup de grace. Instead of a viable conservative candidate opposing the Obama agenda, and 30 years of Clintonian lies, we have Trump turning over the keys to the White House to Hitlery.
The Trumpkins, of course, will blame conservatives, just as Mitt, McCain, and Dole loyalists blamed anyone but their man.
The Republic will probably have to survive 8 more years of progressive rule, before a new party can raise a viable candidate to oppose them. Hint, hint, any past Trump association will forever blacklist politicians who allied themselves with Trump. Look at the history of the Whigs, and you see the history of the GOP, a formerly "Grand ol' Party".
