DES MOINES, Iowa — There are three weeks to go before Iowa kicks off the 2016 presidential campaign, and Donald Trump and Ted Cruz are generating overwhelming enthusiasm among Republican voters in the state.

There's some concern among party professionals who believe both candidates are unelectable in the November matchup against the Democratic nominee, but so far there's not any panic.

Talk of a "takedown" effort aimed at either Trump or Cruz appears to have faded as the Feb. 1 caucuses in Iowa near.

Instead, there's now nervous acceptance that two of the Republican Party's most divisive figures may continue to lead the presidential pack well into the first month of voting.
