First, the new tweet, in which Trump endorsed Cruz, the junior U.S. Senator from Texas, over his Democratic challenger Beto O'Rourke:
I will be doing a major rally for Senator Ted Cruz in October. I'm picking the biggest stadium in Texas we can find. As you know, Ted has my complete and total Endorsement. His opponent is a disaster for Texas - weak on Second Amendment, Crime, Borders, Military, and Vets!— Donald J. Trump (@realDonaldTrump) August 31, 2018
Now, a flashback to Trump's 2016 tweet:
Why would the people of Texas support Ted Cruz when he has accomplished absolutely nothing for them. He is another all talk, no action pol!— Donald J. Trump (@realDonaldTrump) February 28, 2016
How would the latter tweet look on, say, a billboard? Glad you asked!
That rendering comes from a GoFundMe page titled "Texas against Ted Cruz" that was launched on Saturday by a group called USA Latinx. From its fundraising pitch:
We are planning to display the president's own words about Cruz from 2016 on a mobile billboard, to remind Texans of the truth. This is a joint effort initiated by Antonio Arellano in collaboration with Claude Taylor and David Hogg. The money raised by this account will go towards funding the mobile billboard to maximize visibility and impact.
Antonio Arellano is a Houston-based political activist. Claude Taylor is a veteran Democratic political operative who's worked on several presidential campaigns and served in the Clinton White House. David Hogg is a political activist who rose to prominence as a survivor of the Stoneman Douglas High School shooting in Parkland, Florida, earlier this year.
Note the "mobile billboard" clause—which means the group's rendering above doesn't quite show what it actually has planned.
Anyway, in less than two days, the fundraiser worked—raising $9,760 of its $6,000 goal—and is now closed to donations. Hogg has since tweeted that "the billboard is happening" and "thanks to all who contributed" and also released a mock-up of a truck-mounted tweet. (If it's not displaying properly, click on the image in the tweet below.)
Update Here's the first mock-up:— David Hogg (@davidhogg111) September 3, 2018
we are making the billboard mobile so we can follow Trump and Rafael around Texas. Can't wait for y'all to see @POTUS @tedcruz #USA :) #VoteNovember6th pic.twitter.com/qEn1fAiMbJ
"Rafael," by the way, is what Ted Cruz's parents named him (full name: Rafael Edward Cruz).
