BLUE WAVE? Republicans should remain calm about 2018.

According to the FiveThirtyEight Generic Ballot, the Democrats’ lead over Republicans is slowly narrowing. Last December, Democrats led Republicans by a 14-point margin (50 percent to 36 percent). As of this week, their lead has shrunk to six points (46 percent to 40 percent). Fox News has the lead at five points, while Quinnipiac University’s pollsters peg it at just four points.

In nautical terms, a four- to six-point advantage is barely a ripple, let alone a “blue wave.” Republicans should take a deep breath and count their blessings in 2018. Despite the prevailing media narrative, there are many of them.

For starters, Republicans continue to outraise Democrats. In February, the Republican National Committee raised nearly $13 million, breaking its previous February fundraising record. The debt-ridden Democratic National Committee raised less $7 million last month, while seeing its total liabilities rise to over $6 million.

In 2017, the RNC raised $130 million — more than twice the DNC’s haul. Much of it came from digital fundraising, as Republicans added more than one million email addresses in the last quarter of 2017 alone. The RNC is also expected to double the small-dollar donation database that raised more than $250 million for President Trump in 2016. The RNC’s counterparts at House and Senate campaign arms are breaking similar fundraising records.

Fundraising remains solid, but conservative sentiment is likely tepid after last month’s budget-busting budget deal.
