If Trump's proposal to upgrade/finish the Wall is so abhorrent to Democrats, why did not President Obama demolish the already existing sections?

Where was the concerted effort by those opposed to a wall to remove it?

Trump's specific promise was not to upgrade/finish a wall - it was specifically to build one the height of a stadium and make Mexico pay for it.

He promised a lot of other things too.

Now watch him change his tone and manner and quickly backpedal on everything he said that his party disagrees with.

Politically, the end always justifies the means.

You are indulging in a fair bit of Wishful thinking there rache. If your right, you should love him, he be an Obama clone, & another catastrophe.

I doubt he'll manage half his promises, however if he just stop the climate & alternate energy rort, cleans out the Clinton criminal network, & sorts out the EPA he will be worth every bit of the effort that put him there.

If he opens up the US oil & coal capacity, then tells the middle east to go jump, & sort themselves out, he will have been a great president, one of the greatest.

The wall will be built. In terms of core promises this is the 'core-est'.

It won't be 55' high. Or even 30' high. But it will be built and the Latino illegal crossings will be drastically reduced if not stopped. In terms of payment, you won't see a cheque from the Mexican govt to cover the costs. But a thousand little fees on remittances from the US to Mexico and visa fees and the like will be imposed and/or increased to cover the costs

Ya reckon? I reckon those wily Mexicans will dig tunnels under it. If it gets built at all, which I doubt, because there are a few other problems with the idea:

$25 billion is still $25 billion. If the US can't afford it (they can't) how the hell can Mexico?

It won't work, but it was never meant to work as an actual physical barrier to stop Mexicans. It was meant to win Trump votes, a task in which it succeeded admirably, and can now be dispensed with.

I certainly hope he builds the wall, but I don't see how he can make Mexico pay for it. Whatever the cost, it is worth it to Americans to keep illegals out. A high wall and machine-gun equiped watch towers are the only way to stop the invasion. Given the success of the Great Wall of China in ancient times, it should be a doddle for modern America.
