Buoyed by a significant drop in faith for Republicans, Democrats have widened their gap of support to largest they've had in two years, 45 percent to 38 percent, according to a new poll.

The unpopularity of President Trump has helped to torpedo the Republicans, who fell from a high of 42 percent on Election Day, according to Gallup.

The Democrats held steady, though didn't expand their support in the new poll.

According to the authoritative pollster:

The growing Democratic advantage in recent months is mostly attributable to a decline in Republican affiliation rather than an increase in Democratic affiliation. Since November, the percentage of Republicans and Republican leaners has fallen four percentage points, while there has been a one-point rise in Democratic identification or leaning. The Republican decline has been offset mostly by a three-point increase in the percentage of Americans with no party preference or leaning.

President Donald Trump's unpopularity is likely a factor in the Republican Party's falling fortunes. The president's job approval rating generally has held near 40% since February -- well below average for presidents historically, and especially for those in their first few months in office.

Gallup said that it is an understatement to report that the numbers are good for Democrats.

"Party identification and political independents' party leanings are major predictors of individual vote choice. At the national level, party affiliation is related to the outcomes of midterm elections. The current seven-point Democratic edge in party affiliation is similar to what it was in 1998 and 2006, the two strongest Democratic years among the most recent midterm elections," said Gallup.

But, it cautioned, Dems have to also expand their base or the GOP could comeback.
