Why does the left insist on conflating two separate issues, abortion and welfare?  Because they know, whether or not they will admit it, that science proves life begins at conception, i.e., abortion is murder.  To be anti-life is a losing argument.  To disregard this form of murder, they attempt to make the issue something else; providing for all those poor pregnant women and their unwanted children.  If we can't or won't use government to forcibly take income from hard-working people who earned it, who want the freedom to use their own money for their own families, then the murder of the innocent unborn is our only option.  Really?  That's the same mentality that tells people and governments it's OK to eliminate homelessness by killing the homeless, you know, something fascist and Marxist countries have done in the past.
Needy mothers and children are no excuse for murdering innocents.  Abortion numbers are down, not because of liberal policy, but despite them.
