I can not paste and keep the HTML format in the Article editor

When creating an article I am adding the paragraph section and then trying to copy from another webpage .  If copy anything I only get the text but if i paste it into word or another  editor it keeps all the formatting Really poor editor the you can not even paste into it 

Hello,

You must clear HTML formatting before pasting. To do this, paste to Notepad first (Windows) or TextEdit (Mac), and then copy from there and paste to the editor.
