A few short weeks ago, the Democrats thought they had a chance to win Texas as part of a master plan to gain control the Senate. Today, however, that looks decidedly improbable at best. The Senate race in Texas, which had been competitive and even showed Democratic challenger Beto O’Rourke ahead in one poll amid record fundraising, now has seen incumbent Republican Ted Cruz Rafael (Ted) Edward CruzCruz blocks amended resolution honoring Ginsburg over language about her dying wish Trump argues full Supreme Court needed to settle potential election disputes Press: Notorious RBG vs Notorious GOP MORE extending his lead to close to 10 points.

Other Senate races that were once thought to be close, and possibly winnable by Democrats, have seen a similar progression in the last few weeks. Nevada has gone back and forth between Democrat Jackie Rosen and Republican Dean Heller Dean Arthur HellerOn The Trail: Democrats plan to hammer Trump on Social Security, Medicare Lobbying World Democrats spend big to put Senate in play MORE, with the latest poll showing a slight lead by Heller after a period where Rosen had a narrow but consistent margin.

In Arizona, the same pattern is observable.

Put another way, Democratic hopes of winning the Senate are literally evaporating each day, and the lead that they have in the House has gone from 31 seats to 26 seats, according to Real Clear Politics average.

My best guess today is that Democrats will lose a few seats in the Senate, win the House very narrowly, a much less auspicious prognostication than I and most close observers expected just two to three weeks ago.
