The Democrats do not want that wall, and in order for it to be approved you need 2/3 of the majority of Congress to vote for it, so no.
However, with the way the president is throwing a tantrum and threatening to close the govt down some more, even for "years", then they may consider an alternative to a wall that may not cost as much, before he has a heart attack.
Where did you get your information on saying "the majority" of Americans want the wall? Did you read a consensus or are you just making this up because it is your feeling the majority want it? I've seen no such thing on the news so my feeling is that's your opinion and not a fact.
My bad-- you need a bipartisan approval to have that bill pass in the Senate, not 2/3 of the majority. That only applies to some other actions such as impeachment, or getting rid of a member of Congress. Still, without the democratic vote it will be a "no".
The only true wisdom is in knowing you know nothing.
