Looks like they are still using landlines as part of their method:
To reach those who have abandoned traditional landline telephones, Rasmussen Reports uses an online survey tool to interview randomly selected participants from a demographically diverse panel.
They claim to offset this with various corrections, but it seems landlines are the only numbers they call.
I highly doubt they’d be crappy enough to keep that up. Nobody does polls like that now

Very much still in use.
