If Cruz is worried about unenthusiastic Republicans, he should look at his own vote on the budget

"Do not be deceived, God is not mocked; for whatever a man sows, that he will also reap."
Galatians 6:7

Ted Cruz over the weekend:

U.S. Sen. Ted Cruz is preparing Texas Republicans for a turbulent election year amid super-charged Democratic enthusiasm — including in his own re-election campaign.

....

Addressing the Fort Bend County GOP on Friday night, Cruz warned of an "incredible volatility in politics right now," calling Democrats "stark-raving nuts" in their opposition to Trump. He pointed to Trump's recent State of the Union address and Democrats' reluctance to applaud, saying the scene "underscores the political risk in November."

"Let me tell you right now: The left is going to show up," Cruz said, delivering the keynote address at the party's Lincoln Reagan Dinner. "They will crawl over broken glass in November to vote."

Maybe.

It's possible we will face a challenging general election environment.  Democrats are livid.  Republicans are, at best, inconsistent.

But what possible reason could Republican voters have to not care?!?

The massive two-year budget deal proposed by Senate leaders Wednesday raises budget caps by $300 billion in the next two years, increases the debt ceiling and offer up nearly $90 billion in disaster relief for hurricane-ravaged Texas, Florida and Puerto Rico.

About $165 billion would go to the Pentagon and $131 billion to non-defense programs.

"Our members who are focused on the military are very happy where we landed with that," Ryan told Hewitt on his radio show in reference to the defense spending caps.

The debt ceiling will be raised by the appropriate amount until March 2019.

And who, pray tell, voted for the spending bill?!?

After much consideration, I will reluctantly vote for this legislation. It contains major victories; if hurricane relief & restoring vital defense spending were the only elements of this bill, I would be supporting it energetically & enthusiastically. -> https://t.co/1ma5tWzZPK

Bottom Line: It's still too soon to tell what the environment will look like in November, but if you're wondering why Republicans might stay home in large quantities, actions like last week's spending bill stunt would be a good place to start.
